Abstract
The use of bioproducts is an alternative to minimize the indiscriminate use of anthelmintics to control worms in livestock. This study evaluated the effects of oral administration of two commercial formulations, based on the fungus Duddingtonia flagrans (Bioverm®) and D. flagrans associated with Pochonia chlamydosporia, on the control of worms in naturally infected cattle on February pasture. to October 2021. Eighteen Holstein x Zebu cattle were divided into groups of six animals (group 1 Bioverm®, group 2 Association® and control), separated into paddocks naturally infected with helminth larvae (L3). Collection of feces samples to determine parasite load and pasture samples to determine L3 infestation. The study demonstrated low recovery of L3 in the pasture due to low rainfall during the experiment. The EPG was lower in groups 1 and 2 compared to the control in April, May and July, while in March the values were lower only in treatment 1 compared to the control. The individual or combined administration of fungal products reduced the release of eggs and the presence of larvae in pastures in certain months of the year, indicating their effectiveness in the strategic control of gastrointestinal parasites in cattle.
